\n" ); document.write( "42=2(2W-3)+2W
\n" ); document.write( "42=4W-6+2W
\n" ); document.write( "6W=42+6
\n" ); document.write( "6W=48
\n" ); document.write( "W=48/6
\n" ); document.write( "W=8 ANS. FOR THE WIDTH.
\n" ); document.write( "L=2*8-3
\n" ); document.write( "L=16-3=13 ANS. FOR THE LENGTH.
